Replace locally-defined duplicate interfaces in page.tsx,
CandleChart.tsx, SpanAnnotationManager.tsx, Toolbox.tsx,
SpanAnnotationList.tsx, and SpanPopover.tsx with imports from @/types.
- SpanAnnotation, SpanLabelType: replaced in all 6 files
- Candle, AnnotationType: replaced in CandleChart.tsx, SpanAnnotationManager.tsx, Toolbox.tsx
- Annotation (with geometry): replaced in CandleChart.tsx and Toolbox.tsx
- Chart: kept local in page.tsx (shared type has created_at: Date|number vs local number)
- Annotation in page.tsx: kept local (geometry: any) but added missing color field for compatibility

Add shared Candle interface with time, open, high, low, close, and
optional volume fields. Volume is optional because the DB schema does
not store volume but the predict/patterns API routes accept it as an
optional field.
Mark task 9.1 as complete in tasks.md.

Move the inline 'new Set<string>()' default prop to a module-level constant
(EMPTY_STRING_SET) to prevent unnecessary Set instance creation on every render,
which could cause unnecessary re-renders in children or effects that depend on
reference equality.
Replace inline magic numbers (8px, 60s, 2, 1, 0.15, 0.25, 100) and hardcoded
color strings with named module-level constants for better maintainability and
clarity. Organized constants into logical groups:
- Magic number constants (tolerance, intervals, sizes, alphas)
- Dark theme colors
- Light theme colors
- Candlestick colors
- Prediction overlay colors
- Predefined label colors
This improves code readability and makes it easier to adjust UI parameters globally.
